Ingredients You’ll Need

The Fruit Base

• 3 Ripe Bananas – Sliced to provide a soft, creamy foundational layer.
• 20 oz Crushed Pineapple – Must be drained to ensure the cake doesn’t become too “soupy.”
• 21 oz Strawberry Pie Filling – Provides the vibrant color and sweet-tart glaze for the fruit.

The Cake Crust

• 1 box Yellow Cake Mix – Acts as the “flour” and “sugar” base that transforms into a golden crust.
• 3/4 cup Unsalted Butter – Melted and drizzled to hydrate the cake mix and create a rich, shortbread-like texture.

Toppings and Extras

• 1 cup Chocolate Chips – For those essential pockets of melted cocoa.
• 1/2 cup Chopped Nuts & 1/2 cup Mini Marshmallows – Adds crunch and a toasted, gooey finish.

The Iconic Garnish

• Vanilla Ice Cream, Whipped Cream, & Maraschino Cherries – Non-negotiable for achieving that authentic “Banana Split” experience.

Step-by-Step Instructions

Prep the Oven and Dish Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or non-stick spray to prevent the fruit sugars from sticking.

Build the Fruit Foundation Arrange the sliced bananas evenly along the bottom. Layer the drained pineapple over the bananas, then spread the strawberry pie filling over the top. Use a spatula to smooth the surface so the fruit is evenly distributed.

Apply the “Crust” Sprinkle the dry yellow cake mix evenly over the fruit. Crucial Tip: Do not stir! You want the dry mix to sit on top of the fruit to create the cobbler texture.

Hydrate with Butter Slowly and carefully drizzle the melted butter over the entire surface of the cake mix. Try to cover as much of the dry powder as possible; this is what turns the mix into a golden crust.

Add the Toppings Evenly sprinkle the chocolate chips, chopped nuts, and mini marshmallows over the buttered cake mix.

Bake to Perfection Bake uncovered for 40–45 minutes. The cake is ready when the fruit is bubbling at the edges and the top is a deep golden brown. If you see dry spots of cake mix after 30 minutes, drizzle a tiny bit more melted butter on those areas.

Garnish and Serve Let the cake cool for at least 10–15 minutes so the fruit filling can set slightly. Scoop while warm into bowls and top with a massive scoop of vanilla ice cream, a dollop of whipped cream, and a cherry.

Recipe Notes & Tips

• The “No-Stir” Rule – Resist the urge to mix the layers. Keeping the cake mix on top is the only way to achieve the distinct “dump cake” crunch.
• Drain the Pineapple – If you leave the juice in, the bottom of the cake will be watery. Press the pineapple into a colander to remove as much liquid as possible.
• Butter Coverage – If you find drizzling difficult, you can slice cold butter into very thin pats and cover the surface of the cake mix entirely. Both methods work well.
• Banana Ripeness – Use bananas that are just starting to spot. Overly mushy bananas will disappear into the sauce, while slightly firm ones maintain their shape.

Perfect Pairings

• Cold Milk – The classic accompaniment for any rich, chocolatey cake.
• Caramel Drizzle – Add a bit of caramel sauce over the whipped cream for an “Extra Loaded” version.
• Fresh Strawberries – Serve with a few sliced fresh berries on the side to brighten the cooked fruit flavors.
• Strong Hot Coffee – The bitterness of the coffee cuts through the intense sweetness of the pie filling and marshmallows.

Ideal Occasions

• Summer Potlucks – A crowd-pleasing dessert that feels like a party in a pan.
• Kids’ Birthday Parties – It’s interactive, colorful, and features flavors that almost every child loves.
• Family Sunday Dinner – The ultimate “set it and forget it” dessert that bakes while you eat your main course.
• Last-Minute Guests – Uses shelf-stable pantry items (cake mix, canned fruit, chocolate chips) for a quick gourmet-style result.

Storage & Serving Tips

• Refrigeration – Store leftovers in the fridge for up to 4 days. The bananas may darken slightly, but the flavor will remain delicious.
• Reheating – This cake is best served warm. Reheat individual portions in the microwave for 20–30 seconds to soften the fruit and melt the chocolate.
• Freezing – While you can freeze this cake for up to a month, the texture of the bananas can become somewhat grainy upon thawing.
• Room Temp Serving – If serving at a party, it can sit at room temperature for a few hours, but the “melted ice cream” effect is best achieved when the cake is warm.

Creative Variations to Try

• Chocolate Overload – Use a chocolate cake mix instead of yellow for a “Death by Banana Split” version.
• Neapolitan Style – Use a white cake mix and add a few drops of strawberry extract to the butter for a pinker, fruitier crust.
• Nut-Free Version – Simply omit the nuts or replace them with crushed graham crackers for a different kind of crunch.
• Coconut Tropical Twist – Add a 1/2 cup of shredded coconut to the topping for a “Toasted Hawaiian” profile.

Troubleshooting Common Issues

• Dry Flour Pockets – This is caused by uneven butter distribution. Use a spoon to “pat” the butter into the dry mix if you see white spots forming during the bake.
• Too Sweet – If you prefer a less sugary dessert, use a “sugar-free” cake mix or find a pie filling with “no sugar added.”
• Soggy Bottom – Ensure the fruit layers aren’t too deep and that the pineapple was drained. A 9×13 dish is the correct size to ensure the liquid evaporates properly.
• Burnt Toppings – If the marshmallows are browning too fast, loosely tent the dish with aluminum foil for the last 15 minutes of baking.

Why This Recipe Works

The Banana Split Dump Cake succeeds due to capillary action and fruit reduction. As the butter melts, it travels through the dry cake mix (capillary action), hydrating the starches and fats to form a solid crust. Simultaneously, the moisture from the fruit boils beneath the crust, partially steaming the underside of the cake while reducing the fruit juices into a thick, concentrated syrup. At 380 calories, this dessert provides a high-energy, high-sugar treat that is perfectly balanced by the fat in the whipped cream and ice cream.

Final Thoughts

This Banana Split Dump Cake is a masterpiece of efficiency, proving that you don’t need a pastry degree to make a dessert that everyone will talk about. It’s a fun, colorful, and deeply satisfying bake that brings a bit of “ice cream shop” magic into the home kitchen.
